Arcos de la Frontera is a town and municipality in the Sierra de CÃ¡diz comarca, province of CÃ¡diz, in Andalusia, Spain. It is located on the Northern, Western and Southern banks of the Guadalete river, which flows around three sides of the city under towering vertical cliffs, to Jerez and on to the Bay of CÃ¡diz.
Roman ruins also exist in the area. Arcos became an independent Moorish taifa in 1011 during the protracted collapse of the Umayyad Caliphate of CÃ³rdoba. Arcos was associated with the Jerez by 'Abdun ibn Muhammad who ruled from c. 1029/1030 to 1053. The region was overtaken by the Almoravid dynasty in 1091.
